Hi! I'm a PhD student in the Machine Learning Department at CMU where I am fortunate to be advised by Pradeep Ravikumar and Andrej Risteski. I graduated from CMU with degrees in computer science and statistics & machine learning. Before entering grad school I spent two years as a software engineer at Google NYC where I worked on Search Infrastructure.
I'm broadly interested in the theoretical foundations of machine learning as a basis for human intelligence; in particular, I focus on robustness, representation learning, and out-of-distribution generalization. I work to develop principled formal analyses of the statistical and algorithmic properties of these tasks and possible approaches to solving them.
